If you've purchased the Bambu Labs Speed Controller, like me you'll notice it doesn't have a case, so I designed one that hardly adds any bulk to it, but protects the internals.  It uses the hardware that comes with the controller.

To assemble:

1. Screw the support pillars to the fan speed plastic/glass cover using the supplied hardware. (as shown in the picture)
2. Insert into the case the panel supplied (not the metal one) (see picture)
3. Insert the controller into the case, USB male connector first.  It's a snug fit so you may need to manouver it a little.
4. Put on the plastic glass cover, then screw it from the bottom using the provided screws.
5. …and voila!

Feedback is always welcomed :)
